Constructor Detail

BookmarkData

public BookmarkData(BookmarkTree bookmarkTree)

Create a new bookmark data object. This should only be called by the bookmark-tree item because it has no idref item that needs to be resolved.

Parameters:

bookmarkTree - fo:bookmark-tree for this document

BookmarkData

public BookmarkData(Bookmark bookmark)

Create a new pdf bookmark data object. This is used by the bookmark-items to create a data object with a idref. During processing, this idref will be subsequently resolved to a particular PageViewport.

Parameters:

bookmark - the fo:bookmark object

BookmarkData

public BookmarkData()

Create a new bookmark data root object. This constructor is called by the AreaTreeParser when the element is read from the XML file

BookmarkData

public BookmarkData(java.lang.String title,
                    boolean showChildren,
                    PageViewport pv,
                    java.lang.String idRef)

Create a new bookmark data object. This constructor is called by the AreaTreeParser when a element is read from the XML file.

Parameters:

title - the bookmark's title

showChildren - whether to initially display the bookmark's children

pv - the target PageViewport

idRef - the target ID

Method Detail

getIDRef

public java.lang.String getIDRef()

Get the idref for this bookmark-item

Returns:

the idref for the bookmark-item

addSubData

public void addSubData(BookmarkData sub)

Add a child bookmark data object. This adds a child bookmark in the bookmark hierarchy.

Parameters:

sub - the child bookmark data

getBookmarkTitle

public java.lang.String getBookmarkTitle()

Get the title for this bookmark object.

Returns:

the bookmark title

showChildItems

public boolean showChildItems()

Indicator of whether to initially display child bookmarks.

Returns:

true to initially display child bookmarks, false otherwise

getCount

public int getCount()

Get the size of child data objects.

Returns:

the number of child bookmark data

getSubData

public BookmarkData getSubData(int count)

Get the child data object.

Parameters:

count - the index to get

Returns:

the child bookmark data

getPageViewport

public PageViewport getPageViewport()

Get the PageViewport object that this bookmark refers to

Returns:

the PageViewport that this bookmark points to

isResolved

public boolean isResolved()

Check if this resolvable object has been resolved. A BookmarkData object is considered resolved once the idrefs for it and for all of its child bookmark-items have been resolved.

Specified by:

isResolved in interface Resolvable

Returns:

true if this object has been resolved

getIDRefs

public java.lang.String[] getIDRefs()

Get the array of idrefs of this resolvable object. If this object contains child resolvables that are resolved through this then it should return the idref's of the child also.

Specified by:

getIDRefs in interface Resolvable

Returns:

the id references for resolving this object

resolveIDRef

public void resolveIDRef(java.lang.String id,
                         java.util.List<PageViewport> pages)

Resolve this resolvable object. This resolves the idref of this object and if possible also resolves id references of child elements that have the same id reference. This method allows the Resolvable object to resolve one of its unresolved idrefs with the actual set of PageViewports containing the target ID. The Resolvable object initially identifies to the AreaTreeHandler which idrefs it needs resolved. After the idrefs are resolved, the ATH calls this method to allow the Resolvable object to update itself with the PageViewport information.

Specified by:

resolveIDRef in interface Resolvable

Parameters:

id - an ID matching one of the Resolvable object's unresolved idref's.

pages - the list of PageViewports with the given ID

getName

public java.lang.String getName()

Return a human-readable name for this ODI (for error messages, etc.)

Specified by:

getName in interface OffDocumentItem

Specified by:

getName in class AbstractOffDocumentItem

Returns:

String name of ODI
